/**
 * A method that does the work to handle getting a set of configs via REST API.
 *
 * The following query string parameters are supported:
 * - string/string[]: can be a string or an array
 *
 * The response will include a config key that is an array of requested configs.  Configs
 * that are not public or are not defined will be filtered out, and request will still succeed.
 * This is to make it easier to request configs that maybe defined in some versions of MantisBT
 * but not others.
 *
 * Note that only users with ADMINISTRATOR access can fetch configuration for other users.
 *
 * @param \Slim\Http\Request $p_request The request.
 * @param \Slim\Http\Response $p_response The response.
 * @param array $p_args Arguments
 * @return \Slim\Http\Response The augmented response.
